Introduction
The teacher is a very dominant and most important factor in formal education in general. Teachers are educators and teachers of role models and even self-identification figures. Therefore, teachers should have adequate behavior to be able to develop themselves completely [1].
Teachers play an important role in the educational process, therefore the needs of teachers need attention. Teachers need to get guidance and facilities at work so that teacher needs are met. If the teacher's needs are met, the teacher will feel satisfied at work. Job satisfaction will affect teacher productivity and performance, and both directly and indirectly have an impact on the quality of learning.
In line with the results of [2] which concluded that job satisfaction has a positive effect on teacher performance. It can be interpreted that the existence of good principal leadership and optimal teacher empowerment will strengthen the effect of job satisfaction on teacher performance. For this reason, the principal in increasing teacher job satisfaction can be done through: 1). Creating an atmosphere that can support increased teacher satisfaction, for example by providing learning facilities and equipment; 2). Creating a harmonious relationship between teachers through various informal activities such as holding field trips, sports competitions and others.
Supervision can be carried out by the principal or by supervisors who carry out their main duties and functions to guide and supervise the education unit. This is in line with the results of research conducted [3], there is a significant positive relationship between principal supervision and teacher job satisfaction.
Based on the results of this study, it means that the supervision carried out by the principal can increase teacher satisfaction at work. If the supervision carried out by the principal or supervisor can increase teacher professionalism, teacher job satisfaction can increase.
Achievement of optimal teacher job satisfaction is influenced by internal and external factors. Internal factors, namely the drive to work, responsibility for the task, interest in the task. Meanwhile, external factors are respect for assignments, opportunities for development, attention from school principals, interpersonal relationships among teachers, training, guided discussion groups, and library services [4].
The success of education in schools is largely determined by the success of the principal in supervising the teaching staff at school. The principal is one component of education that is very influential in increasing teacher job satisfaction. The principal is responsible for the provision of education, school administration, manpower development, and maintenance of facilities and infrastructure.
Apart from the importance of the problem of academic supervision, there are still things that will affect teacher job satisfaction, namely the work environment. Teachers will be able to carry out their duties properly if supported by a good work environment too. A healthy, comfortable, and conducive work environment will be able to increase teacher productivity so that it will increase teacher job satisfaction. But in reality, not all schools have a conducive environment. Some elementary schools in the Betung sub-district are located right on the edge of the main road, often side by side with busy centers such as markets. This is of course very influential on the teaching and learning process itself.
The work environment is everything that is around the workers and which can affect them in carrying out their assigned tasks, for example cleaning, music, lighting and others [5].
There are many factors that affect the level of job satisfaction of a worker in carrying out activities that have been charged by the school. Principal's academic supervision factor needs to be considered in an effort to create job satisfaction because it is related to the perception of the worker concerned. In addition to the academic supervision of the principal, work environment factors also influence the level of job satisfaction. The conducive work environment felt by workers will create job satisfaction for them in their activities.
Research conducted [6] shows that: 1) Academic Supervision has an effect on the performance of Mathematics teachers, 2) The Work Environment affects the performance of Mathematics Teachers, 3) Academic Supervision and Work Environment jointly affect the Performance of Economic Teachers.
Researchers made observations in several schools in SD Negeri in Betung District. From these observations, the researcher found that teachers do not have adequate work space. It is said to be inadequate because the teacher's office is not very large but must be divided into three rooms, namely the teacher's office, administration room, and the principal's room. Even though the teacher should have enough space to be able to work comfortably. If these environmental factors are not considered properly, it is feared that teacher performance will also not run as it should. The teacher will also feel lazy to come to the office, the teacher will not carry out his duties as a teacher to the fullest.
Based on the above problems, according to the author, "The Effect of Principal Academic Supervision and the Work Environment on Teacher Job Satisfaction at Public Elementary school all Betung District" is important to be studied.
The purpose of this study was to identify, describe, and analyze the effect of principal academic supervision and work environment on teacher job satisfaction at Public Elementary school all Betung District.

A quantitative approach is used to examine a particular population or sample by using a random sampling technique [7]. Collecting data using statistical analysis instruments, with the aim of testing the hypothesis set.
The population in this study were 192 Public Elementary school teachers in Betung District, with a sample of 116 people. Data collection techniques through questionnaires / questionnaires, observation and documentation.

The significant level of the Principal Academic Supervision variable (X1) is 0,000 smaller than the α value (0,05), thus H0 is rejected and Ha is accepted, so it can be concluded that the Principal Academic Supervision variable (X1) has a significant effect on teacher job satisfaction (Y) in Public Elementary school in Betung District.

This means that if supervision activities are carried out by the principal, it can increase teacher job satisfaction and vice versa. This is in accordance with the theory of "supervision is complex role in professional education. with an all-important mission of improving the learning experience for students, that role remains constant despite changes in schools [10]. In other words, supervision has a complex role in building education into a professional with a mission to improve the learning experience or learning quality for students, even though changes in schools occur because of the supervision process carried out. So, it can be concluded that the effect of principal supervision on teacher job satisfaction indicates that if the supervision of the principal is implemented it will make a real contribution to increasing teacher job satisfaction. Here there is a match between the results of the research and existing theories. In other words, the results of this study support existing theories.

The significant level of the Work Environment variable (X2) is 0,000 smaller than the α (0,05), thus H0 is rejected and Ha is accepted, so it can be concluded that the Work Environment Variable (X2) has a significant effect on teacher job satisfaction (Y) in Public Elementary school in Betung District.

Based on the results of multiple linear regression calculations, it is known that the constant is 35,590, meaning that if the academic supervision of the principal and the work environment is zero, then the teacher's performance is 35,590. The regression coefficient of the principal's academic supervision variable is 0,040, meaning that if the principal's academic supervision has increased by one unit, the teacher's performance will increase by 0,040, assuming other independent variables are of fixed value. Because the regression coefficient is positive, it can be said that the principal's academic supervision (X1) has a positive effect on teacher job satisfaction (Y). The regression coefficient for the work environment variable is 0,530, meaning that if the work environment has increased by one unit, the teacher's job satisfaction will increase by 0,530 units, assuming the other independent variables are of fixed value. This means that Principal Academic Supervision and Work Environment always have a positive increase in teacher job satisfaction.
